RESUMO

AIM: To provide a comprehensive and more representative national data on the disease, especially on treatment options and outcomes, and to determine access of retinoblastoma patients from Luzon, Visayas and Mindanao to eye care, and determine if access is associated with delay in consultation, staging and outcomes. METHODS: Cohort study of retinoblastoma patients seen in eleven institutions located in the three major areas of the Philippines namely Luzon, Vizayas and Mindanao from 2010-2020. RESULTS: Totally 636 patients, involving 821 eyes, were included. Majority (57%) were from Luzon and were seen in institutions in Luzon (72%). Annually, 58±10 new cases were seen with 71% having unilateral disease. Median delay of consultation remained long at 9 (3, 17)mo, longest in patients with unilateral disease (P<0.02) and those from the Visayas (P<0.003). Based on the International Retinoblastoma Staging System, only 35% of patients had Stage 1 while 47% already had extraocular disease. Enucleation was the most common treatment received by 484 patients while intravenous chemotherapy was received by 469. There were 250 (39%) patients alive, 195 (31%) dead, 85 (13%) abandoned, 17 (3%) refused and 89 (14%) with no data. CONCLUSION: This study presents the largest cohort of retinoblastoma patients in the Philippines in terms of patients' and participating institutions' number and geographical location and type of institution (private and public). It also presents more comprehensive data on the treatments used and outcomes (survival, globe salvage, and vision retention rates). Delay in consultation was still long among patients leading to advanced disease stage and lower survival rate. Despite increasing capacity to diagnose and manage retinoblastoma in the country, the delay of consultation remains long primarily due to accessibility issues to eye care institutions especially in the Visayas and financial concerns. The delay was still significant that overall survival rate remain low.

RESUMO

To compare the effectiveness at ten years of follow-up of radical prostatectomy, brachytherapy and external radiotherapy, in terms of overall survival, prostate cancer-specific mortality and biochemical recurrence. Cohort of men diagnosed with localized prostate cancer (T1/T2 and low/intermediate risk) from ten Spanish hospitals, followed for 10 years. The treatment selection was decided jointly by patients and physicians. Of 704 participants, 192 were treated with open radical retropubic prostatectomy, 317 with 125I brachytherapy alone, and 195 with 3D external beam radiation. We evaluated overall survival, prostate cancer-specific mortality, and biochemical recurrence. Kaplan-Meier estimators were plotted, and Cox proportional-hazards regression models were constructed to estimate hazard ratios (HR), adjusted by propensity scores. Of the 704 participants, 542 patients were alive ten years after treatment, and a total of 13 patients have been lost during follow-up. After adjusting by propensity score and Gleason score, brachytherapy and external radiotherapy were not associated with decreased 10-year overall survival (aHR = 1.36, p = 0.292 and aHR = 1.44, p = 0.222), but presented higher biochemical recurrence (aHR = 1.93, p = 0.004 and aHR = 2.56, p < 0.001) than radical prostatectomy at ten years of follow-up. Higher prostate cancer-specific mortality was also observed in external radiotherapy (aHR = 9.37, p = 0.015). Novel long-term results are provided on the effectiveness of brachytherapy to control localized prostate cancer ten years after treatment, compared to radical prostatectomy and external radiotherapy, presenting high overall survival, similarly to radical prostatectomy, but higher risk of biochemical progression. These findings provide valuable information to facilitate shared clinical decision-making.Study identifier at ClinicalTrials.gov: NCT01492751.

RESUMO

OBJECTIVES: This study aimed to develop mapping algorithms from the Expanded Prostate Cancer Index Composite (EPIC) and the Short-Form (SF) Health Surveys to the Patient-Oriented Prostate Utility Scale (PORPUS), an econometric instrument specifically developed for patients with prostate cancer. METHODS: Data were drawn from 2 cohorts concurrently administering PORPUS, EPIC-50, and SF-36v2. The development cohort included patients who had received a diagnosis of localized or locally advanced prostate cancer from 2017 to 2019. The validation cohort included men who had received a diagnosis of localized prostate cancer from 2014 to 2016. Linear regression models were constructed with ln(1 - PORPUS utility) as the dependent variable and scores from the original and brief versions of the EPIC and SF as independent variables. The predictive capacity of mapping models constructed with all possible combinations of these 2 instruments was assessed through the proportion of variance explained (R2) and the agreement between predicted and observed values. Validation was based on the comparison between estimated and observed utility values in the validation cohort. RESULTS: Models constructed with EPIC-50 with and without SF yielded the highest predictive capacity (R2 = 0.884, 0.871, and 0.842) in comparison with models constructed with EPIC-26 (R2 = 0.844, 0.827, and 0.776). The intraclass correlation coefficient was excellent in the 4 models (>0.9) with EPIC and SF. In the validation cohort, predicted PORPUS utilities were slightly higher than those observed, but differences were not statistically significant. CONCLUSIONS: Mapping algorithms from both the original and the abbreviated versions of the EPIC and the SF Health Surveys allow estimating PORPUS utilities for economic evaluations with cost-utility analyses in patients with prostate cancer.

RESUMO

PURPOSE: Long-term comparative effectiveness research on localized prostate cancer treatments is scarce, and evidence is lacking especially for brachytherapy. The aim of this study was to assess the long-term impact of the side effects of radical prostatectomy, brachytherapy, and external radiation therapy on patients with localized prostate cancer at 10 years, using propensity score analyses. METHODS AND MATERIALS: This was a prospective observational study of a cohort of men who received a diagnosis of clinically localized prostate cancer (clinical stage T1 or T2, low and intermediate risk group) and were treated with radical prostatectomy (n = 139), brachytherapy (n = 317), or external radiation therapy (n = 194). Treatment decisions were jointly made by patients and physicians. Patient-reported outcome (PRO) evaluation included the Expanded Prostate Cancer Index Composite and Short Form-36, administered centrally by telephone interviews before and annually after treatment. The Expanded Prostate Cancer Index Composite covers urinary, bowel, sexual, and hormonal domains. To assess PRO changes over time, while accounting for correlation among repeated measures, generalized estimating equation models adjusted by propensity scores were constructed. RESULTS: The PRO completion rate at 10 years was 85.8%. Generalized estimating equation models showed that the pattern of radical prostatectomy side effects, with substantial urinary incontinence and sexual dysfunction, remained until 10 years after treatment (standard deviation [SD], -1.1 and -1.3, respectively). Brachytherapy produced late deterioration in urinary continence (SD, -0.4) and sexual function (SD, -0.9) that appeared midterm, but the differences from radical prostatectomy remained statistically significant at 10 years (P < .001 after adjusting by propensity score). External radiation therapy showed similar results to brachytherapy, but with bowel bother (SD, -0.3). CONCLUSIONS: Although late deterioration in radiation therapy groups attenuated differences from radical prostatectomy, relevant PRO differences still remained after 10 years. Our findings support that brachytherapy is the treatment option that causes the least impact on PROs; it is therefore an alternative to be considered when making evidence-based decisions on localized prostate cancer treatment.

RESUMO

Objetivos: A epidemiologia da depressão resistente ao tratamento (DRT) varia mundialmente, mas é incerta na América Latina. Este artigo relata a epidemiologia e o ônus da DRT em pacientes com transtorno depressivo maior (TDM) no Brasil, no estudo observacional multinacional, multicêntrico, de DRT na América Latina (TRAL). Métodos: Trezentos e noventa e seis pacientes adultos com TDM (tratados ou não) no Brasil, com diagnóstico de TDM usando o Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) e confirmado por MINI Entrevista Neuropsiquiátrica Internacional v7.0.2, foram incluídos em 10 centros. Os pacientes forneceram consentimento e concluíram as avaliações. Os critérios de exclusão incluíram pacientes com psicose, esquizofrenia, transtorno bipolar, transtorno esquizoafetivo, demência, transtorno de uso de substância ou participação atual em outro estudo. A MADRS foi usada para gravidade da doença. Escalas de depressão e instrumentos classificados pelos pacientes foram usados para medir os resultados. Resultados: A prevalência de DRT em pacientes com TDM na América Latina corresponde a 29,1% (IC 95% [26,8%; 31,4%]), embora no Brasil corresponda a 40,4% (IC 95%: 35,6%-45,2%), a mais alta no estudo TRAL. Os pacientes com DRT são mais velhos e apresentam maior proporção de divórcios e menor nível educacional, com pontuação mais alta na Escala de Classificação da Depressão de Montgomery-Asberg (MADRS), comparados a pacientes sem DRT. Os custos de saúde foram maiores em pacientes com DRT, com menor qualidade de vida e maiores custos de saúde e comprometimento laboral. Conclusões: Estes achados confirmam que a DRT apresenta alta prevalência no Brasil, consistentemente com estudos anteriores sobre transtornos depressivos. Globalmente, os pacientes com DRT apresentam maior ônus da doença, sugerindo a necessidade de melhorar os cuidados para pacientes com DRT no Brasil


Objectives: Treatment-resistant depression (TRD) epidemiology varies worldwide, but uncertain in Latin America (LatAm). This paper reports on the epidemiology and burden of TRD in major depressive disorder (MDD) patients in Brazil from the TRD in America Latina (TRAL) multicenter, multinational, observational study. Methods: 396 adult patients (treated or untreated) with MDD diagnosis in Brazil using Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) and confirmed by MINI International Neuropsychiatric Interview v7.0.2 were consecutively enrolled from 10 clinical sites in Brazil. Patients provided consent and complete assessments. Exclusion criteria included patients with psychosis, schizophrenia, bipolar disorder, schizoaffective disorder, dementia, with substance use disorder or currently participating in another clinical trial. Montgomery-Asberg Depression Rating Scale (MADRS) was used for disease severity. Depression scales and patient rated instruments were used to measure outcomes. Results: The prevalence of TRD in MDD patients in LatAm is 29.1% (95%CI [26.8%; 31.4%]), though the values for Brazil are 40.4% (95%CI: 35.6%-45.2%), the highest in the TRAL study. TRD patients are older, have higher proportion of divorce and lower education, with higher MADRS score compared to non-TRD patients. Healthcare costs were higher in TRD patients, with lower quality of life (QoL) and higher work impairment and healthcare costs. Conclusions: Present findings confirms that TRD is highly prevalent in Brazil, which is consistent with previous studies concerning depressive disorders. Globally, TRD patients experience higher burden of the disease. These findings suggest the need to improve care among TRD patients in Brazil

RESUMO

OBJECTIVE: We studied an unusual case of global aphasia (GA) occurring after brain tumor removal and remitting one-month after surgery. After recovering, the patient reported on her experience during the episode, which suggested a partial preservation of language abilities (such as semantic processing) and the presence of inner speech (IS) despite a failure in overt speech production. Thus, we explored the role of IS and preserved language functions in the acute phase and investigated the neuroanatomical underpinnings of this severe breakdown in language processing. METHOD: A neuropsychological and language assessment tapping into language production, comprehension, attention and working memory was carried out both before and three months after surgery. In the acute stage a simplified protocol was tailored to assess the limited language abilities and further explore patient's performance on different semantic tasks. The neuroanatomical dimension of these abrupt changes was provided by perioperative structural neuroimaging. RESULTS: Language and neuropsychological performance were normal/close to normal both before and three months after surgery. In the acute stage, the patient presented severe difficulties with comprehension, production and repetition, whereas she was able to correctly perform tasks that requested conceptual analysis and non-verbal operations. After recovering, the patient reported that she had been able to internally formulate her thoughts despite her overt phonological errors during the episode. Structural neuroimaging revealed that an extra-axial blood collection affected the middle frontal areas during the acute stage and that the white matter circuitry was left-lateralized before surgery. CONCLUSIONS: We deemed that the global aphasia episode was produced by a combination of the post-operative extra-axial blood collection directly impacting left middle frontal areas and a left-lateralization of the arcuate and/or uncinated fasciculi before surgery. Additionally, we advocate for a comprehensive evaluation of linguistic function that includes the assessment of IS and non-expressive language functions in similar cases.

RESUMO

The Institute of Medicine recommended that all patients receive survivorship care plans (SCPs) post-treatment to improve quality of follow-up care. However, little is known regarding how survivors utilize SCPs and the congruency between providers' and survivors' perspectives. Feedback from colorectal cancer survivors (in receipt of a personalized/individualized SCP) and oncology providers was obtained via interviews. Survivors noted SCPs benefits of reduced duplicative procedures and cancer worry with the synthesized treatment information. Providers noted billing/reimbursement and time investiture (for form completion) as potential barriers. Further investigation of SCPs is warranted regarding utility prior to widespread adoption in follow-up care.

RESUMO

BACKGROUND: Radiotherapy (RT) plays an important role in the multidisciplinary management of Ewing's Sarcoma (ES), especially in unresectable cases. AIM: Assessment of efficacy of RT in terms of local control in pediatric patients with primary ES of bone. MATERIALS AND METHODS: Thirty-six patients younger than 17 years old with ES treated with combined RT and chemotherapy with (N = 14) or without (N = 22) prior surgery from 1981 to 2008 were retrospectively reviewed. Since 1995, they were all treated according to the Spanish Society of Pediatric Oncology protocol (55.5% cases). Those patients received vincristine, ifosfamide, doxorubicin and etoposide. The TNM classification was as follows: 17 T1, 18 T2 and 1 T3; 36 N0; 29 M0, 5 M1a and 2 M1b. Analysis was stratified by treatment: definitive RT or pre/postoperative RT. RESULTS: The 36 patients (21 male; 15 female) had a median age of 10 years (range 2-17 years). Median follow-up of living patients was 105 months. The 2-year local control (LC) rate for all patients was 88%. Five-year LC rates for patients treated with definitive and pre/postoperative RT were 91% and 86%, respectively. Two-year overall survival and disease-free survival rates for all patients were 68% and 66%, respectively. Low phosphatase alkaline levels and local and distant recurrences were significantly predictive of worse prognosis (P = 0.021, P = 0.011, P = 0.007, respectively). CONCLUSION: Radiotherapy with and without surgery is a highly effective local treatment option in the multidisciplinary management of ES in pediatric patients.

RESUMO

BACKGROUND: Attempts to improve survival outcomes of patients with high risk Ewing's sarcoma (ES) have focused on chemotherapy dose intensification strategies. AIM: The objective of this study is to retrospectively evaluate clinical characteristics and outcome of pediatric patients with high risk ES treated at a single institution. MATERIALS AND METHODS: From 1995 to 2008, seventeen patients (male:female, 14:3) were treated with dose-intensive therapy in our institution. Median age at diagnosis was 10 years (range: 2-15). Seven patients had metastases at diagnosis (lung in 6 cases and bone in one case). Eleven patients presented with unresectable disease. Fifteen (88.2%) received the Spanish Society of Pediatric Oncology protocol which includes six cycles of vincristine, doxorubicin, ifosfamide and etoposide. Two out of the six cases that were resectable received postoperative radiation. In addition, eleven patients received definitive radiation therapy. Finally, twelve (70.5%) out of 17 patients received myeloablative therapy with melphalan/etoposide. The rest of patients (N = 5) received busulfan/melphalan. RESULTS: Median follow-up was 78 months (range: 15-155 months). Initial responses were complete in all patients, but 9 of them developed progression disease. Seven patients became long-term event-free survivors. No patient died of toxicity after transplantation. The 2- and 5-year overall survival rates for all patients were 93% and 73%, respectively. Event-free survival rates were 74% and 54% at 2 and 5 years, respectively. CONCLUSION: This single-institution experience suggests that myeloablative therapy against high risk ES is effective and safe.

RESUMO

OBJETIVO: Conocer edad, sexo, desplazamiento, escolaridad, actividad desarrollada, jornada laboral, vivienda en calle y cobertura de seguridad social de un grupo de niños que laboran en las calles de las capitales latinoamericanas. MATERIAL Y MÉTODOS: Estudio de corte transversal. Se aplicó un cuestionario a 972 niños que trabajan en las calles de Bogotá, Ciudad de Guatemala, Ciudad de México, Quito y San Salvador; RESULTADOS: El 63.3 por ciento era de sexo masculino; 39 por ciento provenía de familias desplazadas; 18 por ciento habitaba en la calle; 62 por ciento trabajaba más de 40 horas a la semana; 19 por ciento tenía seguridad social, y 32 por ciento se dedicaba al comercio ambulante. Se encontró que la mayoría de las variables se comportan de forma significativamente diferente para cada ciudad. CONCLUSION: El trabajo infantil ambulante es una actividad peligrosa, de largas jornadas laborales, con exposición a múltiples factores de riesgo, y se comporta de manera significativamente diferente en cada ciudad estudiada. Esto sugiere que las soluciones al problema deben diseñarse caso por caso.


OBJECTIVE: To identify the age, sex, mobility, education, work activity, working hours, street dwelling, and social security coverage in a group of children working in the streets in capital cities in Latin America. MATERIAL AND METHODS: Cross sectional study. A questionnaire was applied to 972 children working in the streets of Bogotá, Guatemala City, Mexico City, Quito and San Salvador. RESULTS: A total of 63.3 percent subjects were boys; 39 percent were children from displaced families; 18 percent lived in the streets; 62 percent worked more than 40 hours per week; 19 percent were covered by the social security system, and 32 percent were street vendors. The behavior of variables differed significantly by city. CONCLUSION: Child labor in the streets is a dangerous activity characterized by long working hours and exposure to risk factors. Child work has different characteristics in each of the cities studied, which suggests that the solution to the problem must be designed on a case by case basis.
